Configuring settings for the local network
IP Address
Enter an IP address for your phone. This IP address allows your phone to be reached by
other subscribers in your local network (e.g., PC).
The IP address comprises 128 bits and is represented by eight blocks of hexadecimal
figures from 0 to FFFFFF that are separated by a colon, e.g.,
2001:b021:189:0:205:5dff:fe6b:87.
The IP address comprises a prefix and an interface identifier. The length of the prefix
(usually 64 bits) is determined by the Prefix Length value.
Prefix Length
The prefix length stipulates how many bits of the IP address are used for the network
prefix. Enter the prefix length that is used in your network.
Preferred DNS Server:
Enter the IP address for the preferred DNS server. DNS (Domain Name System) allows
you to assign public IP addresses to symbolic names. The DNS server is required to con-
vert the DNS name into the IP address when a connection is being established to a
server.
You can specify the IP address for your router/gateway here. This forwards address
requests from the phone to its DNS server.
There is no default setting for a DNS server.
Alternate DNS Server:
Enter the IP address for the alternate DNS server that should be used in situations
where the preferred DNS server cannot be reached.

Once all the settings are complete, press the display key
tion settings.

VLAN tagging

A local network can be divided into logical subnetworks, so-called VLANs (Virtual Local
Area Network, standard IEEE 802.1Q). Multiple VLANs share a physical network and its
components, e.g., switches. Data packets of a VLAN are not forwarded to another VLAN.
VLANs are often used to separate the data traffic of different services (Internet telephony,
Internet TV, ...) and to define different priorities for the data traffic.
If you are operating your phone in a VLAN, enter the identifier of your VLAN (VLAN tag)
here. You get this from your network operator.
Warning
If you enter an incorrect value here, you must reset the phone to its default settings
£
( Page 81). After this you must re-establish phone access to the local network.
